Electrophysiology of linguistic performance: evidence for a double dissociation in fluent and non-fluent aphasia
P. 50–51.
Aphasia, a language impairment following stroke or brain trauma, is normally manifested behaviorally. Patients with the so-called non-fluent aphasia experience major difficulties at the level of morphosyntax (that is, producing and comprehending complex morphology and syntax). In contrast, patients with fluent aphasia predominantly show problems at the lexical-semantic level (that is, accessing word forms and lexical semantics). However, a few studies have proven that the language deficit in patients with aphasia is expressed not only in their linguistic performance, but also in specific electrophysiological responses.
In healthy individuals, incongruencies at different linguistic levels cause distinct event-related brain potentials (ERPs) registrated at the scalp. Syntactic incongruency elicits the ELAN and the P600 potentials, lexical-semantic incongruency elicits the N400 potential. Critically, in standard for those potentials linguistic contexts the lack of N400 was reported for fluent patients, while the lack of the ELAN and a reduced and delayed P600 – for non-fluent patients (Friederici et al. 1998, Wassenaar and Hagoort 2005). These findings support the idea of electrophysiological brain mapping on specific linguistic problems observed in different aphasia types.
The study was aimed at further investigating electrophysiological evidence for the suggestion that spoken sentence comprehension problems in individuals with fluent and non-fluent aphasia are caused, at least partly, by breakdowns at different levels of language processing – lexical-semantic and morphosyntactic respectively. To test this, we performed a study in healthy and aphasic Russian individuals using the method of event-related potentials (ERPs) that has become a powerful tool in addressing temporal aspects of language processing.

The aim of this study was to evaluate the potential use of the frequency-following response (FFR) for assessing preserved perception of simple speech stimuli in humans. To this end, event-related potentials (ERPs) elicited by isolated Russian syllables were recorded and analyzed in 29 healthy subjects in two frequency ranges, the standard range (1—40 Hz) and ...

Технологии автоматического распознавания речи (АРР) к настоящему моменту стали базовым компонентом бэкенд-инфраструктуры различных голосовых и когнитивных ассистентов, обеспечивая доступ пользователей к коммерческим сервисам и государственным платформам. Однако из-за неравномерного распределения данных, на которых модели АРР обучаются, острой становится проблема предвзятости моделей при работе с атипичной речью. Цель исследования заключается в оценке качества распознавания и сравнении ...

The effects of emotional distraction might differ depending on the valence and arousal of induced affective states. Nevertheless, insufficient complexity of a cognitive task might affect the ability of participants to allocate attention resources for the successful examination of emotional stimuli and task performance. This is why, in previous research, indicators of accuracy and response ...

Background.
The problem of the relationship between thinking and speech is fundamental for psychological science: it underlies
the understanding of formation and functioning of human consciousness, marked by its speech form. The study of aphasia is one
of the promising areas of research into the relationship between these functions, which also has important practical significance
in the field of ...

Introduction. The existing speech production schemes do not fully reflect the interaction of speech perception systems and one’s own internal speech. The study is aimed at comparing the connection between internal pronunciation and phonemic perception using psychophysi-ological methods. Methods. Twenty-five people took part in the EEG study. The subjects were offered auditory stimuli, and then ...

When we speak, selecting the right word takes longer whenever its semantic associates become active simultaneously. Although such semantic interference (SI) activates the left inferior frontal gyrus (LIFG), its lesions do not systematically increase SI induced by written word distractors. Therefore, whether the LIFG plays a causal role in resolving SI remains an open question. ...

Умение работать с противоречиями считается одной из характеристик здоровой психики и признаком сформированности высших форм мышления. Несмотря на обилие работ, в которых восприятие противоречий изучается с использованием метода электроэнцефалографии, исследований, посвященных поиску связей между нейрональными коррелятами реакций на противоречивую информацию и конкретными психологическими характеристиками, в том числе когнитивными, недостаточно. Мы проверяли гипотезу о том, что электрофизиологическая реакция на предъявление ...

Purpose
Long-term language recovery after left-hemisphere glioma surgery varies substantially across patients. We investigated how well it can be predicted using clinical variables such as the postoperative decline in language processing, tumor grade, resection volume and location, extent of resection, and intraoperative language mapping. Beyond predicting the overall recovery, we examined which domains of language processing ...

Background
Persons with aphasia (PWAs) are often impaired in time reference/tense production. It has been suggested that this impairment is due to encoding or/and retrieval deficits. However, to the best of our knowledge, no experimental design that enables teasing apart selective encoding and retrieval deficits has been proposed thus far.
Aims
This study aims at disentangling time reference-related ...

Понятие «салиентность», получившее широкое распространение в англоязычной литературе, посвященной шизофрении, дословно переводится как «заметность» или «значимость». Чаще всего оно употребляется в сочетании «аберрантная салиентность», под которым понимают присвоение ложной значимости малозначительным фактам и деталям. Менее распространено понятие «адаптивная салиентность», под которым понимают «правильное» присвоение значимости биологически важной информации. Считается, что при шизофрении имеет место снижение адаптивной салиентности в сочетании с тенденцией к аберрантной салиентности. Понятия аберрантной и адаптивной салиентности ...
